The favorite box is definitely frustrating. I've ended up with 5 eggs in one box and 1 each in two others and one box empty occasionally. Mostly, I've seen lower-ranked hens get bullied and pecked out of a box and that motivated me to make more available. It has definitely helped reduce noise and stress (drama).I average 20 potential layers. I currently have 10 nesting boxes. To me it's not a matter of ratios. There are nesting boxes on the floor now where hens have laid on the floor. If they want to lay on the floor I'll give them a nest to lay in on that spot. Sometimes they use them, sometimes they do not. There are times I feel like ripping out all nests but the current favorite, lol. Then a few days later they all choose a different favorite nest! Who knows the mind of a chicken?![]()
The higher and lower boxes is likely a good idea. I can see younger/lower ranked hens being more likely to jump to the upper boxes, but haven't tested the theory.
